ABSTRACT:
A motion control system includes an inverter adapted to receive electrical power at a first DC voltage level and selectively provides power to a motor. A first DC--DC converter receives electrical power at the first DC voltage level and provides electrical power at a second DC voltage level. A second DC--DC converter receives electrical power at the second DC voltage level and provides electrical power at a third DC voltage level. A controller receives electrical power at the third DC voltage level and provides control signals to the inverter. A switching circuit is connectable to a second source of power and provides electrical power to the second DC--DC converter when the second DC voltage is less than a selected threshold.
